Les parois parallèles, qui peuvent engendrer, dans les petits espaces, des "échos flottants" (allers-retours multiples et perceptibles à l'oreille de réflexions sonores entre deux parois parallèles, si les réflexions ne sont pas déviées ou amorties par des éléments diffusants et absorbants) et des « échos francs », dans les volumes importants, (lorsque la différence des trajets entre son direct et son réfléchi est supérieure à environ 14 m, induisant un décalage temporel perceptible).

flutter echo
Could it be this?
Flutter Echo. A condition that occurs in acoustic spaces when two parallel surfaces reflecting sound between one another are far enough apart that a listener hears the reflections between them as distinct echoes. The audible effect is in many cases a sort of “fluttering” sound as the echoes occur in rapid succession.

resounding echoes
A possible alternative to 'clear', since if they are not damped, they 'resound' or 're-sound'. OED has resounding as "Of a place: to ring or re-echo with sound."
